That's not a blog being hosted by WordPress.COM and you are posting to the wrong support forum. WordPress.com and WordPress.org are completely separate, have different log-ins and run different versions of themes with same names. http://support.wordpress.com/com-vs-org/

We provide support only for free hosted WordPress.COM blogs and not for WordPress.org software installs. If you don't have a username account at WordPress.ORG click http://wordpress.org/support/ and register one on the top right hand corner of the page that opens, so you can post to the support forums there and receive advice from WordPress.ORG bloggers.
